產品描述: | GSK1016790A (GSK101)是一種新型的、有效的TRPV4激活劑,其在人脈絡叢上皮細胞中的EC50為34 nM |
靶點: |
hTRPV4(In HEK cells):2.1 nM; mTRPV4(In HEK cells):18 nM;CalciumChannel;?TRP/TRPVChannel |
體外研究: |
在濃度為1 nM以上時,GSK1016790A在表達鼠源和人源TRPV4的HEK細胞中引發鈣離子(Ca2+)的流入(EC50分別為18和2.1 nM),引起劑量依賴式的TRPV4全細胞電流的激活。它可以在多種類型細胞中刺激、激活TRPV4,包括內皮細胞、尿路平滑肌細胞、尿道上皮細胞、以及過表達TRPV4的HEK293細胞。GSK1016790A特異性激活TRPV4,引發質膜上該通道的表達下調、快速部分脫敏 |
體內研究: |
GSK1016790A在高肺血管張力的情況下,使全身系統的血管阻力以及肺部血管阻力急劇下降[3]。GSK1016780A激活TRP4,引起血管舒張、滲漏和組織出血 |
細胞實驗: |
Cell lines: 脈絡叢上皮細胞 Concentrations: 10 nM Incubation Time: 20分鐘 Method: 用DMSO、10 nM GSK處理或者預先處理以1 mM HC、再用10 nM GSK處理CPECs(脈絡叢上皮細胞)20分鐘。處理過后,這些細胞被固定、用Coomassie Brilliant Blue進行染色 |
動物實驗: |
Animal Models: Adult male Sprague-Dawley rats Dosages: 2, 4, 6, 8, 10, and 12 μg/kg Administration: 靜脈注射 |
